Dell 3020 (Micro) 1440P HELP!

I have a Dell Optiplex 3020 micro, currently on Catalina with OpenCore 0.57
Used this thread: https://www.reddit.com/r/hackintosh/comments/gcfcv6/dell_optiplex_3020m_catalina_10154_opencore_057/

Borrowed the EFI-folder and all work flawlessly except I can not get 1440P no matter what I do. Tried different Mac model, extension via hack tool to allow override in resolution...

Any tip? This is the exact EFI-folder: https://app.box.com/s/5kmgsle97lilg758l8dao30qafzy5oqq

I have i5 4590T with HD 4600.
